Default So how much power does an oil filled radiator actually use.

are swing doors classed as barriers of some sort.?


What do you think? Can the heat move freely through the doors when
they are closed?


Not according to the fire regs, but the doors are mostly left open, UNLESS there is a lecture going on it that room which happens perhaps 2-4 times a week, or a meeting is there or theres too much noise(audio, drilling etc) coming from that area then we close the doors.


So, as I said previously, the presence of the swing doors may not
impact the calcs if the temperatures are roughly the same on both
side. The chances are that will be more likely when the doors are open
rather than closed.

yuo've not given any tols just talked crap.


And did John Rumm talk crap, as he also gave you the tools?


There were no tools that were any use unless you can account for those variables.


And you can account for them by going 'worst case'.

A professional is someone that is paid to make these calculations and can understand both theory and practice.

But it doesn't require 'a professional', just someone with more than
one brain cell.

which is exactly why you can't do it.


Bwhahaha. Oh, you are funny dave (in a very sad way).


You say John Rumm has given the tools if that is the case why canl;t you use those, can you at least explain that.


Yes, I can, very easily. No. The answer is 'no' because I don't have
the measurements and U values for the construction of your lab.

\You;re excuse is that yuor not going to help, isn;t it,


How many times have I told you that if you do the bit that only you
can do, 'we' might be able to help you.

in reality it means yuo can;t help,


In reality you are right. (see above).

Well Sherlock, if you are saying that is what one windows actually is
then size then that would be a start. Then we need to know if it is
single / double / triple glazed and we can make a stab at it's thermal
properties.


I don't know those properties other than it is triple glazed.


So you know it is triple glazed but can't find a way to work out how
big it is?

Previously the windows were single galzed and I;ve no idea ofm the original design for calculating the heatign system ahad single glazed windows were even included in the original design or not.


Irrelevant to what you are trying to do now.

The windows also havent been sealed yet and I don't know how much differnce that makes, I can hear the person in the next office NOT through the walls but through where the windows meet at the edges.


That would make a big difference ... and something you might have
mentioned sooner.

I can't sort of predict how many students will come through the door,


It doesn't matter for the ball park figures.

I can;lt predict how often the builders will leave teh exteranl doors open or for how long during the day or night.


Presumably that won't be happening indefinably?

As I've tried to expain there are too many variables of which I have no control overv and one of the biggest is the weather.


Understood ... but you haven't even offered the information up for
those things you can measure. And as far as the weather goes, again
you calculate for the typical worst case. If the heaters can get the
lab(s) up to 20 DegC in one hour when it's 0 DegC outside it can do it
when it's 5 or 10 outside.

So, are you going to carry on running away or start wandering around
with a notebook and tape measure?


So I don;t really know what relivance window size has.


Of course you don't, like you don't have a clue about most of
anything. How do you think you consider the losses through any of the
different materials unless we know how much of each material there is?

Seriously, a child could work that out.


Prove it then.


OK, I get that you don't have the first clue about any of this but
rather than continuously arguing and trying to catch me (and others)
out (that will never happen), why don't you just get on with answering
the questions we have put to you and seeing if we can help you take it
further?

Until you do that you will still be part of the problem, not the
solution.
